At the start of Steal a Brainrot, you have a small amount of money to begin building your base. Purchase your first Brainrots from the conveyor belt and let them start generating passive income. This early investment lays the foundation for future expansion, allowing you to buy stronger and more valuable Brainrots as you earn more money.

Inside your base, navigate to collect money from your existing Brainrots, and reinvest that money in higher-tier characters. Top-tier Brainrots cost more but provide significantly greater income over time, making them essential for rapid progression. Balancing the purchase of new Brainrots while managing your current collection is key to maximizing profits.
